TRUCK-SUPPORTER FOR RAILROAD-CARS. I

SPECIFICATION forming part of Letters Patent No. 538,661, dated May '7, 1895.

Application filed March 24, 1894.

To all whom it may concern.-

Be it known that I, HARRY A; DAVIS, of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and usefullmprovement in Truck-Supporters for Railroad- Cars, of which the following is a specification.

My invention relates, generally, to railroadcar trucks, and particularly to devices for raising and supporting the same from the car :0 to which they are attached, and it has for its object to provide a simple, durable and inexpensive device, readily attachable to the car, for raising and supporting the truck in its raised position to relieve an overheated axle box and journal of the weight of the truck while the car is in motion, and also to raise the truck to enable the removal and replacing of brasses, and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a side elevation of one end of a car, partly broken away, provided with my improved. device; Fig. 2, an end elevation of the samepartly broken away; Fig. 3, detail views of a stirrup or hanger-iron and the bar; Fig. 4, a detail view of the turnbuckle, and Fig 5 a detail View ofthe pulley-bar.

Similar letters refer to similar parts throughout the several views.

A represents a railway car, and B an ordinary car truck on which the car is mounted in the usual or any desired manner. The frame of the truck is provided with the ordinary iron truss C at each side in which guides are secured to receive the axle boxes, all of which may be of the usual construction and need no further description here.

D represents a metal bar, preferably cylindrical, the ends of which are supported in hangers or stirrups, E, the upper ends of which are bent over, as at a, to form an angular hook adapted to fit over, one each, of the adjacent longitudinal sills, b, of the car frame, sothat said bar bears at each end against said sills and. is thereby prevented moving longitudinally in the stirrups or hangers; In the split or divided end of a short bar, F, a grooved wheel, 0, is mounted loosely on a pin, d, which is held in place by a key so as to be readily Serial No. 504,968. (No model.)

removable, the other end of said bar being A screw-threaded and adapted to enter a screwthreaded perforation formed in the end of a link G which is connected at its other end to a screw-eye H by means of a similar perforation in the link the threads of which are reversed, whereby said link forms a turn-buckle by which a chain, I, attached to said screweye may be raised or lowered; The wheel, 0, is fitted over the bar D and is free to move back'and forth thereon, and the lower end of the chain suspended therefrom is provided with a link a by which it may be connected to a hook-shaped projection f formed on the end of the lower tie bar of the truss C. I prefer, however, to replace one of the tie bolts connecting the upper and'lower tie bars of the truss with an eye-bolt, g, as shown at the left hand side, Fig. 1, to which I connect the end of the chain.

From the above description it will be observed that the device may be speedily applied to a car and attached to its truck,'one at each end of the truck at each side of the car, and that by simply turning the link G the chain may be tightened to raise the truck 0d of any particular axle box or journal and that the car may be moved while the truck is so raised or supported, thereby relieving the axle box and journal of the weight of the truck and giving an overheated journal and box a chance to cool off while the train is in motion; also my device may be used in lieu of a jack to raise the truck to remove or replace brasses.

The arrangement of the bar, D, and the wheel, 0, permits of the latter having a free movement to accommodate itself to the motion of the car in rounding curves.

Having thus described my invention, what 4 [0 sisting of a chain, a turn buckle therein, a

wheel connected to said turn buckle, a bar supported by the car for said wheel, and means for connecting the chain and the truck frame, substantially as and for the, purpose described.
